Concept Search - What can I type?

For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.

Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

Abstract

Disclosed is a method for capturing objective information about the usability of an online computer application. It involves having the operating system maintain records of the number of times each panel is displayed as well as the number of times the user presses the help key while it is displayed. This statistical information is then consolidated and transmitted back to the application designers.

Quality Control Mechanism for Computer User Interface
Design

Disclosed is
a method for capturing objective information about
the usability of an online computer application. It involves having
the operating system maintain records of the number of times each
panel is displayed as well as the number of times the user presses
the help key while it is displayed. This
statistical information is
then consolidated and transmitted back to the application designers.

The quality
of the user interface in a data processing system
is difficult to establish objectively.
What a programmer may
consider to be a logical panes design and conversation structure may
in fact be confusing or error-prone.
Even if standards are developed
and followed, there is no easy way to determine if they are
appropriate in every case. The user's
perception of the quality and
usability of a system may not conform to the assumptions upon which
the standards are based. There is
typically a lack of feedback that
might allow the interface standards to be calibrated.

The
assumption is made that the best designs are those in which
the function is self-evident. From the
standpoint of human factors
engineering, all other things being equal, one design is considered
to be better than another if:

1. A novice user
is able to navigate through the basic function
without extensive training.
2. An experienced user is able to
perform more complicated tasks
correctly the first time.
3. Extensive user documentation is not...
